Any help on FHttpModule?

Hi! I implemented FHttpModule and IHttpRequest, it sends RPC calls to external application, gets reply, all working fine. BUT, I get many problems after some usage time (windows, latest unreal build)

For example, if I start spawning many requests, FHttpModule simply stops accepting them until I hit ‘stop’.
Sometimes even after stop, and then hitting play, requests are still stuck.

I suppose FHttpModule or my requests are not shutting down properly in editor or something.

Is there any example of using it properly? And advises on how to set up everything for smooth and seamless workflow?

Or the only way is to learn everything by trial-and-error?
